The device includes a diverter having a lower opening and an upper opening, the upper opening having a central axis; and a seal having a seal opening, the seal opening being configured to contact an outer surface of the roof-penetrating pipe and form a gas-tight seal with the roof-penetrating pipe. In an assembled state of the device, any of the gas that enters the diverter can only exit the diverter through the upper opening or through the roof-penetrating pipe, and the diverter is installable in multiple different positions, each of the different positions having a different included angle between the central axis of the upper opening and the central axis of the roof-penetrating pipe.

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application No. 62/307,919, filed Mar. 14, 2016, which is incorporated by reference in its entirety.

FIELD

The present invention relates to pipe diverting systems. Particular embodiments of the invention relate to systems and methods for diverting a ventilation pipe on a roof so that another system, such as a solar panel array, can be accommodated.

BACKGROUND

Many commercial and residential buildings have pipes, such as plumbing vent stacks, that penetrate the building's roof and extend vertically a required distance from the roof surface. This distance can be several inches to a foot or more.

With the high cost of electricity in many areas, roof mounted solar panels are becoming increasingly more popular and are even mandated in some jurisdictions.

Most jurisdictions have building department guidelines or codes that determine how a solar panel array can be positioned on a roof including the required distance between the roof surface and the underside of the panels. On occasion, roof-penetrating pipes fall directly in line with a desired panel layout. The minimum required distance that the outlet of the pipe must be above the roof surface is usually greater than the desired (or required) distance between the roof surface and the solar panels. As a result, panel layouts are designed to avoid these pipes when possible, but in some cases it is not possible to position the panels so that every pipe is avoided. Therefore, the solar panel layout is often designed with voids where no panels can be placed so that the pipe can extend the required distance above the roof surface. The result is open areas of seemingly unusable prime power production space, resulting in lower overall power production.

Moving the roof-penetrating pipe from the interior of the attic space and re positioning in another location is time consuming, costly, and, in some cases, impractical or impossible.

Systems and methods for moving the vertical portion of the roof-penetrating pipe without having to move the portion of the pipe that penetrates the roof would allow more uniform and complete solar panel installations without suffering the drawbacks described above. Wasted space would be reduced and panel layout would no longer have to avoid the spots directly above each roof penetration. Higher power output would result as more prime locations would be usable.

SUMMARY

As described above, roof-penetrating pipes can cause undesirable voids in an array of solar panels. Embodiments of the invention solve this problem by providing systems and methods of rerouting the pipe above the roof surface without having to move the portion of the pipe that penetrates the roof.

Embodiments of the invention divert the pipe to one side of any solar panel without the need to move the portion of the pipe that penetrates the roof and close the existing exit hole. The space directly around and above the pipe becomes usable and the array layout can be more consistent and uniform, ultimately using prime space for better power generation.

Embodiments of the invention differ from what currently exists. Layouts currently avoid these pipe exiting spaces as unusable power production space. Embodiments of the invention make theses spaces usable and no longer an obstacle. As a result, additional panels can be set in the prime roof locations resulting in more power production from the array.

DETAILED DESCRIPTION

The following description of the preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.

In the description of embodiments disclosed herein, any reference to direction or orientation is merely intended for convenience of description and is not intended in any way to limit the scope of the present invention. Relative terms such as “lower,” “upper,” “horizontal,” “vertical,”, “above,” “below,” “up,” “down,” “top” and “bottom” as well as derivative thereof (e.g., “horizontally,” “downwardly,” “upwardly,” etc.) should be construed to refer to the orientation as then described or as shown in the drawing under discussion. These relative terms are for convenience of description only and do not require that the apparatus be constructed or operated in a particular orientation. Terms such as “attached,” “connected,” “coupled,” “interconnected,” and similar refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, as well as both movable or rigid attachments or relationships, unless expressly described otherwise. The term “fixed” refers to two structures that cannot be separated without damaging one of the structures. The term “filled” refers to a state that includes completely filled or partially filled.

As used throughout, ranges are used as shorthand for describing each and every value that is within the range. Any value within the range can be selected as the terminus of the range. In addition, all references cited herein are hereby incorporated by reference in their entireties. In the event of a conflict in a definition in the present disclosure and that of a cited reference, the present disclosure controls.

The term “opening” as used in this application can refer to any passageway through which air can travel.

As explained above, it can be beneficial to reroute the above-roof portion of a roof-penetrating pipe in order to accommodate another roof mounted system, such as an array of solar panels.

Embodiments of the invention provide a path for air/gases exiting the, for example, plumbing ventilation pipes of any structure to be diverted from a current location to another more desirable location along the closest edge of any solar panel layout without interrupting the flow of air or minimizing the flow as it escapes into the atmosphere. Embodiments of the invention provide a connection that does not interfere with the solar panels directly above while simultaneously allowing water and debris to freely pass around and under the solar panel without blocking the natural flow of this water, debris and air.

FIG. 1 shows an array of solar panels 30 arranged on a roof 10 of a residential structure. Solar panels 30 are arranged on a plurality of rails 40 in a uniform grid where panels 30 are located in rows and columns. A vent pipe 60 penetrates roof 10 and extends vertically a distance above the surface of roof 10. Due to the height of vent pipe 60, no solar panel can be located above vent pipe 60 and, as a result, a void 50 is created in the array. This void is unsightly and reduces the number of solar panels 30 in the array, which leads to a reduced power output.

FIGS. 2 and 3 show an example of a solar panel array benefiting from an embodiment of the invention. In FIGS. 2 and 3, two solar panels 30 are attached to roof 10 by way of rails 40 and supports 45. Void 50 was required before the use of the invention due to the location of a pipe penetrating roof 10 and extending vertically into void 50. A pipe diverting system 100 is used to reroute the pipe so that another solar panel 35 can be installed as part of the array. In this example, system 100 includes a diverting device 1000 that diverts gases from the pipe to a series of tubes and joints (collectively referred to as a tube system 2000). Tube system 2000 includes a first tube section 2010 that runs substantially parallel to the surface of roof 10 and is attached to diverting device 1000. A first angled tube section 2110 connects first tube section 2010 to a second tube section 2020 in order to change the direction of tube system 2000. Second tube section 2020 is also positioned substantially parallel to the surface of roof 10. A second angled tube section 2120 connects second tube section 2020 to a vertical tube section 2030 in order to route the gases to a vertical exit from tube system 2000. Second tube section 2020 is also positioned substantially parallel to the surface of roof 10. The route of tube system 2000 shown in FIGS. 2 and 3 is just one possible example. Other routes can be taken, such as moving horizontally out of diverting device 1000 to vertical tube section 2030. Other examples can route the gases from diverting device 1000 to a tube section running in the direction of second tube section 2020, then to a tube section running in the direction of first tube section 2010, and then to a vertical tube section. Other examples position diverting device 1000 at an angle other than that shown in FIGS. 2 and 3 and a position pointing 90 degrees to that position. Some jurisdictions may require the pipe sections to flow in such a way that the gases are never forced to travel downward. As a result, an installation where diverting device 1000 is positioned 180 degrees from the position shown in FIGS. 2 and 3 may not be allowed in some jurisdictions. Regardless of jurisdictional requirements, it is preferable in some situations to avoid trapping gas, especially plumbing vent gases, and as a result the gases should not be forced to flow downward. Although the example shown in FIGS. 2 and 3 shows tube section 2030 extending between two solar panels, other examples extend the tubing so that tube section 2030 is outside the array of solar panels.

FIG. 3 shows solar panel 35 in a position that is consistent with a uniform layout of the solar panels. As can be seen from the figures, this was permitted due to the rerouting of the vent pipe made possible by the invention. The installation shown in FIG. 3 not only provides more power than an array without solar panel 35, but it is also more esthetically pleasing.

FIG. 4 shows an example of an embodiment of the invention in a semi-assembled state detached from the roof for illustrative purposes. In FIG. 4, a diverter 1100 (part of diverting device 1000) is shown connected to tube system 2000. In this example, all of the connections between the pieces of tube system 2000 are permanent connections. In the case of polyvinyl chloride (PVC) piping, these connections are made using PVC cement. In the case of other piping, such as acrylonitrile butadiene styrene (ABS) piping, an appropriate permanent cement or other permanent fixing method is used. In some embodiments, some or all of these connections can be non-permanent so that sections can be easily replaced. These connections (permanent or non-permanent) are gas-proof so that the gases cannot exit the pipe anywhere but the exit end of tube section 2030. In the example shown in FIG. 4, the exit end of tube section 2030 is covered by a cap 2040 in order to prevent rain, debris and other unwanted items from entering tube section 2030. Some systems include a cap and some do not. FIG. 4 shows a mounting plate 1300 that is attached to roof 10 as a mounting point for diverter 1100 and a gasket 1200 so that diverter 1100 and gasket 1200 are secured in position over vent pipe 60 in a sealed manner (discussed in detail below). Also shown in FIG. 4 is an example of mounting hardware 2060 for attaching tube system 2000 to roof 10. This example of mounting hardware 2060 includes a plate attached to roof 10 and a strap that attaches a section of tube system 2000 to the plate with screws. Other hardware and methods of securely attaching tube system 2000 to roof 10 can also be used.

FIG. 5 shows the example of diverting device 1000 from FIG. 4 in more detail. A mounting plate 1300 is provided as a foundation for diverting device 1000. Mounting plate 1300 is, in this example, a flat plate that can be attached to roof 10 and then partially covered by roofing material (such as shingles) as shown in FIG. 4. Other examples of mounting plate 1300 can be a shape other than flat to follow the particular contour of other style roofs in order to provide a secure foundation for diverting device 1000. For example, some tile roofs have a wavy configuration which may be better served by a mounting plate having a similarly wavy shape. Whatever the shape of mounting plate 1300, diverter 1100 and gasket 1200 must be properly shaped to form the desired seal with vent pipe 60 (discussed in more detail below). In this example, mounting plate 1300 has six mounting screws 1310 that protrude upwardly from an upper surface of mounting plate 1300. More or fewer mounting screws can be used and mounting fasteners other than screws can be used. Mounting plate 1300 is provided with a hole 1350 through which vent pipe 60 can extend.

A gasket 1200 is provided between mounting plate 1300 and diverter 1100. Gasket 1200 (shown in more detail in FIGS. 19 and 20) creates a gas-proof seal between mounting plate 1300 and diverter 1100 and has a hole that creates a gas-proof seal around vent pipe 60.

Diverter 1100 (shown in more detail in FIGS. 6-11) has a plurality of holes through which mounting screws 1310 extend. In this example, a cap screw 1320 engages with each of the mounting screws 1310 to secure diverter 1100 to mounting plate 1300 (and thus roof 10). Cap screws as shown in this example ensure that the proper spacing between diverter 1100 and mounting plate 1300 in maintained so that gasket 1200 provides a sufficient seal without being crushed. Other securing methods can be used to secure diverter 1100 to mounting plate 1300 as long as they do so in a way that assures that gasket 1200 provides the proper gas-proof seal.

FIGS. 6-11 show more detail of the example of diverter 1100 shown in FIG. 5. In this example, diverter 1100 has a main body 1130 and a base 1110. Base 1110 has a plurality (six in this example) of holes 1120 that accommodate fasteners that secure diverter 1100 to roof 10 (by way of mounting plate 1300). Main body 1130 has sides 1140 and a front face 135. Front face 1135 has an opening 1150. Opening 1150 is configured to receive a tube section (for example tube section 2010 in FIG. 5) and divert gasses from the vent pipe to tube system 2000. As stated above, tube section and opening 1150 are connected in such a way that a gas-proof seal is formed between them. As shown in FIG. 11, the bottom of diverter 1100 has a large opening. This opening is sufficiently large to receive the end of vent pipe 60 (see FIG. 35) in a non-contact arrangement where vent pipe 60 does not contact diverter 1100. Because gasket 1200 forms a gas-proof seal around vent pipe 60, diverter 1100 does not need to form a seal with vent pipe 60. This permits leeway in positioning diverter 1100 relative to vent pipe 60 while still maintaining a gas-proof seal. While the example shown in FIGS. 4 and 5 has opening 1150 of diverter 1100 facing up the slope of roof 10, the above-mentioned leeway allows diverter 1100 to be positioned at any rotational angle relative to vent pipe 60. For example, opening 1150 could face across the slope of the roof (90 degrees from the orientation shown in FIG. 4), or at any other angle. For the proper flow of vented gases from vent pipe 60 without the gases being trapped in tube system 2000 or diverter 1100, some embodiments have opening 1150 facing at least partially up the slope of roof 10.

FIGS. 7, 10 and 11 show protuberance 1160 that extends from the inside of diverter 1100 and has end wall 1165 that acts as a stop feature. End wall 1165 provides a stop that limits how far inside main body 1130 tube section 2010 can extend. By limiting the distance that tube section 2010 can extend inside main body 1130, interference between tube section 2010 and vent pipe 60 is avoided. This can avoid tube section 2010 being pushed too far inside main body 1130 and blocking off, or limiting, gas flow.

The seal provided between vent pipe 60 and gasket 1200 and the seal between diverter 1100 and tube section 2010 create a gas-tight plenum inside diverter 1100 that diverts the gas flow out of the vent pipe in the direction of tube section 2010 without permitting any of the gas from flowing into the space below roof 10. This is done while simultaneously allowing diverting device 1000 to be mounted in many different orientations on roofs of many different pitches. For example, diverting device 1000 can be mounted on a roof having a 6/12 pitch, a 12/12 pitch, or almost any pitch without having to provide any different parts. Also, diverting device 1000 can be mounted in any orientation relative to the slope of the roof without having to provide any different parts.

FIGS. 12-18 show a diverter 1100′ that is another example of a diverter in accordance with embodiments of the invention. Diverter 1100′ is similar to diverter 1100, except that body sides 1140′ are sloped, in contrast to body sides 1140 of diverter 1100. The sloped body sides of diverter 1100′ allow diverter 1100′ to be tilted to a greater degree, as shown in FIG. 18, and still receive the end of vent pipe 60. Such a tilting can be required in an installation where opening 1150 is facing along the slope of the roof as opposed to up the slope of the roof. Diverter 1100′ includes a protuberance 1170 having an end wall 1175. End wall 1175 functions as stops similar to end wall 1165 of diverter 1100.

FIGS. 19 and 20 show an example of gasket 1200 that creates a gas-proof seal with vent pipe 60. Gasket 1200 has a main body 1210 and a plurality (six in this example) of holes 1240 that permit fasteners 1310 to penetrate gasket 1200. Gasket 1200 has an opening 1220, with a sealing edge 1230, through which vent pipe 60 passes. Sealing edge 1230 tightly grips the outside of vent pipe 60 to form a gas-proof seal. Opening 1220 is sized to properly seal around commonly used sizes of ABS and PVC pipes used for vent pipes. Sealing edge 1230 can be formed of the same material as main body 1210 or a different material. Sealing edge 1230 can be formed of a material that is sufficiently flexible and expandable to create the required seal around pipes of different diameters (for example, 2 inch internal diameter and 1½ inch internal diameter).

FIGS. 21-25 show another embodiment of a diverter in accordance with the invention. Diverter 3100 functions similarly to diverter 1100 and diverter 1100′, however the rounded shape of main body 3130 and body sides 3140 can permit greater flexibility in placement of diverter 3100. The rounded main body shape permits diverter 3100 to be rotated and pivoted to a great degree in order to accommodate a wide range of roof pitches and 360 degree rotation around vent pipe 60.

In this example, diverter 3100 has a base 3110. Base 3110 has a plurality (six in this example) of holes that accommodate fasteners that secure diverter 3100 to roof 10 (by way of mounting plate 3300). Main body 3130 has, in addition to body sides 3140, a front face 3135. Front face 3135 has an opening 3150. Opening 3150 is configured to receive a tube section (for example tube section 2010 in FIG. 5) and divert gasses from the vent pipe to tube system 2000. Tube section 2010 and opening 3150 are connected in such a way that a gas-proof seal is formed between them. As shown in FIGS. 21 and 22, the bottom of diverter 3100 has a large opening. This opening is sufficiently large to receive the end of vent pipe 60 (see FIG. 35) in a non-contact arrangement where vent pipe 60 does not contact diverter 3100. Because a gasket 3200 forms a gas-proof seal around vent pipe 60, diverter 3100 does not need to form a seal with vent pipe 60. This permits leeway in positioning diverter 3100 relative to vent pipe 60 while still maintaining a gas-proof seal. While the example shown in FIGS. 4 and 5 has opening 1150 of diverter 1100 facing up the slope of roof 10, the above-mentioned leeway allows diverter 3100 to be positioned at any rotational angle relative to vent pipe 60. For example, opening 3150 could face across the slope of the roof (90 degrees from the orientation shown in FIG. 4), or at any other angle. For the proper flow of vented gases from vent pipe 60 without the gases being trapped in tube system 2000 or diverter 3100, some embodiments have opening 3150 facing at least partially up the slope of roof 10. Although the example shown in FIGS. 21-25 has a plate-like gasket, other types of seals can be used including, for example, a seal that is located within diverter 3100.

FIG. 26 shows an example of a diverting device 4000 that uses multiple tube systems and a distribution box as a diverter. Examples of embodiments such as this can have a seal similar to the gaskets or other seals discussed above with regard to other embodiments. Diverter 4300 is, in this example, formed as a box having an open bottom and an open end 4320. An end plate 4350 is fitted to open end 4320 to provide the number of openings 4370 desired. A plurality (in this example, two) openings 4370 are provided in end plate 4350. A tube system similar to tube system 2000 and including elements 4010, 4110, 4020, 4120 and 4030 is attached in a gas-proof manner to each opening 4370. Flanges 4355 and 4310 are provided on end plate 4350 and diverter 4300, respectively, to facilitate the attachment of diverter device 4000 to the roof. Diverter device 4000 is useful when the vent pipe is a larger diameter than can be run under the solar panels. By providing multiple tube systems, the gas flow of a larger vent pipe can be split into two smaller diameter tube system while not constricting the gas flow. These smaller diameter tube systems can be of a diameter that can fit underneath the solar panels.

FIG. 27 shows an example of an embodiment of the invention is which vent pipe 60 is rigidly attached to diverter 5100 to form a gas-tight seal. Diverter 5100 is attached by way of cement or other joining method to tube section 2010 to form a gas-tight seal. Diverter 5100 is attached to a plate 5300 with a threaded collar 5210 and plate 5300 is attached to the roof. Rigid and/or flexible tubes or pipes can be used in this and any of the other embodiments.

FIGS. 28-35 illustrate one method of installing a diverting device. FIG. 28 shows an existing vent pipe 60 penetrating a roof 10 and having a flashing 6010. FIG. 29 shows flashing 6010 and a collar removed from vent pipe 60. FIG. 30 shows vent pipe 60 being cut off close to the surface of roof 10. The amount of vent pipe 60 left extending above roof 10 is dictated by the shape and dimensions of the diverter being used.
